Old ERA Dad here.
My son attended an MLB Scouting Bureau Showcase in 2012 as a 16 year old (minimum age).
I afforded and opportunity to be seen and heard hitting with wood against INDY, JUCO, D1-D3, and a few baseball fans.
With no metrics and scouts eyes (+ stop watch for throws/60yds), he was identified for further follow. Alas, the SCOUTING BUREAU has been scuttled.
This lead to an AC tryout in PA which was attended by 30+ college coaches from primarily NE schools and Phillies Scouts/Minor League Staffs.
He didn't make the cut, but impressed the group. He received multiple invites to Colleges and was followed during his Jr HS season by multiple area scouts in the New England Area.
He was drafted out of HS, but was not ready for the Minors: He attended an SEC powerhouse and was drafted in 2nd round in 2016.
He now resides in a West Coast AAA as an switch/OF.
If the metrics were in effect in 2012, he would have missed the cut by a long shot.
Moral of the tale: In today's metrics climate, the Player MUST show prowess in game play, because the metrics are fluid.
Bring back the SCOUTS EYES!!!!
